Objective To investigate the effects of low temperature adjustable sodium dialysis combined Astragalus injection in patients with chronic cardiac insufficiency uremia combined the clinical curative effect of dialysis related hypotension .Methods Fourty‐nine patients with uremia combined chronic cardiac insufficiency and suffered repeated dialysis hypotension were involved in this study ,and they were divided into treatment group(n=25) and control group(n=24) .Patients in the control group were treated with hemodialysis for low temperature (35 .5 ℃) ,and sodium curve dialysis ;patients in the treatment group were treated with the same method in that of control group ,and they were treated with astragalus injection 40 mL continuous intravenous drip .Then ob‐serve the blood pressure changes and treatment effect of the two groups of before and after treatment .Results Systolic pressure of the treatment group and the control group was (92 .6 ± 8 .4) and (89 .5 ± 9 .0) mm Hg ,and that of after treatment was (99 .9 ± 8 .0) and (94 .9 ± 9 .3) mm Hg respectively ,the difference before and after treatment in each group was significant (t=3 .147 , 2 .044 ,P<0 .05) ,and the difference of systolic pressure before and after treatment in each group was significant (t=2 .020 ,P<0 .05) .Before the treatment ,the left ventricular ejection fraction score of treatment group and control group was (45 .80 ± 3 .62)%and (46 .01 ± 3 .59)% ,and that of after treatment was (59 .05 ± 3 .15)% and (53 .85 ± 1 .60)% ,respectively ,and the difference be‐fore and after treatment was significant (t=13 .906 ,9 .847 ,P<0 .05) ,and the difference of the left ventricular ejection fraction score after treatment in the two groups was significant (t=7 .328 ,P<0 .05) .Conclusion For patients with uremia combined chronic car‐diac insufficiency and suffered repeated dialysis hypotension ,low temperature adjustable sodium dialysis can significantly reduce the incidence of hypotension in the process of dialysis .But combined huangqi injection in the treatment group could significantly in‐creased the left ventricular ejection fraction ,thus improve the left ventricular function in patients with dialysis .

Objective To investigate the relationship between ambulatory arterial stiffness index (AASI) and left ventricular mass index (LVMI) in the elderly hypertensive patients.Methods This study population consisted of 332 elderly hypertensive patients,who hospitalized in our department from January 2012 to December 2014.AASI was calculated from 24 h ambulatory BP monitoring recordings and LVMI from echocardiography examination.According to the median value of AASI,patients were divided to less than the AASI median group (low AASI group) and equal to or above the AASI median group (high AASI group).Differences between two groups were evaluated using the Student's t-test and Chi-square test.Univariate association was assessed by the Pearson correlation analyses.Multivariate linear regression models were performed to analyze the correlation between AASI and LVMI.Results LVMI was significantly higher in high AASI group compared with low AASI group ((115.91 ±21.36) g/m2 vs.(104.11 ± 17.24) g/m2,P =0.008).Pearson correlation analyses showed that AASI and 24 h pulse pressure were positively correlated to LVMI (r =0.332,P ＜ 0.001;r =0.169,P =0.002).In multivariate linear regression model,AASI(β =44.48,P＜0.001),LDL-C(β =-5.97,P＜0.001) and UA (β =0.02,P =0.045) showed significant association with LVMI.Conclusion AASI independently associated with LVMI,and AASI might be one predictor of left ventricular hypertrophy in hospitalized elderly hypertensive patients.

Objective The aim of this study was to evaluate the glioma using the variety of functional magnetic resonance imaging( fMRI) ,and to perform a more accurate preoperative diagnosis of gliomas. Methods Thirty - five patients with gliomas confirmed by pathology were examined by magnetic resonance imaging (MRI)and functional MRI. Rapid diffusion coefficient(D?),Slow diffusion coefficient(D),perfusion fraction ( f) and distribution diffusion coefficient ( DDC ) in the intravoxel incoherent motion diffusion weighted imaging (IVIM-DWI) were analyzed statistically. Results The mean values of D?,D,f and DDC in the IVIM se-quence of the patients with high-grade of gliomas were statistically significant when compared to the IVIM values of the contralateral normal brain tissues(P<0. 05). Conclusion A variety of magnetic resonance functional im-aging sequences are used to analyze gliomas,which can avoid tumor heterogeneity and improve the recognition a-bility and accuracy of magnetic resonance imaging in high grade gliomas.

Objective:To investigate the concern about pollen broadcasting in Chinese population from multiple dimensions and to understand the information about allergic rhinitis (AR) in China by analyzing related factors.Methods:From March 1 to September 30, 2022, a large-scale multi-center cross-sectional survey was conducted based on the Questionnaire Star platform in 21 Chinese hospitals. A total of 7 056 subjects from 7 regions in China: Northeast, North, East, Central, South, Southwest, and Northwest China were included. Basic characteristics (including social demographic characteristics and disease characteristics of AR patients), concern about pollen broadcasting, the willingness of pollen-induced AR (PiAR) patients to receive pollen broadcasting, and the treatment satisfaction rate of AR patients were collected. The chi-square test, multivariate linear regression model, and Logistic regression analysis were used to analyze the concern about pollen broadcasting in the Chinese population and related factors from multiple dimensions.Results:Among 7 056 subjects, 23.02% were concerned about pollen broadcasting. Among 3 176 self-reported AR and 1 019 PiAR patients, 25.60% and 39.16% were concerned about pollen broadcasting, respectively, which was higher than that of non-AR or non-PiAR subjects ( χ2 value was 21.74 and 175.11, respectively, both P<0.001). Among AR patients, the proportion of spring and autumn allergen-positive patients concerned about pollen broadcasting was higher than that in perennial allergen-positive patients ( χ2 value was 20.90 and 19.51, respectively, both P<0.001). The proportion of AR patients with asthma, sinusitis, allergic conjunctivitis, and cardiovascular and cerebrovascular diseases was higher than those without complications ( χ2 value was 50.83, 21.97, 56.78, 7.62, respectively, all P<0.05). The proportion of AR patients in North China who could find pollen broadcasting locally was 31.01%, significantly higher than those in other regions (all P<0.05). Multivariate linear regression model analysis showed that among PiAR patients, those with higher per capita household income and higher AR disease cognition levels had been concerned about pollen broadcasting in the past, and those complicated with allergic conjunctivitis had stronger intention to receive pollen broadcasting (B value was 0.24, 0.13, 0.66, 0.47, respectively, all P<0.05). The higher the disease cognition level of PiAR patients, the stronger their willingness to actively participate in treatment ( R2=0.72, P<0.001). Only 18.89% of AR patients felt satisfied with the treatment effect. Logistic regression analysis showed that in AR patients, the treatment satisfaction rate was significantly higher among those concerned about pollen broadcasting compared to those who were not ( OR=1.83, P<0.001). Conclusions:Currently, the dissemination of pollen broadcasting in China is hindered by various factors such as disease cognition level. The treatment satisfaction among AR patients remains unsatisfactory.
